For the four successive transition elements (Cr, Mn, Fe and Co), the stability of +2 oxidiation state will be there in which of the following order?
As we learnt in concept no. 10278.
Following is a table showing
(V)
|
Cr
|
Mn
|
Fe
|
Co
|
-0.9
|
-1.18
|
-0.44
|
-0.28

According to the above, the stability order should be:
But is a very strong reducing agent and it gains it's +30.s in aqueous solutions.
the correct order is
Option 1)
This solution is correct
Option 2)
This solution is incorrect
Option 3)
This solution is incorrect
Option 4)
This solution is incorrect
